A new type of gravitational interaction with parity violation and its role in gravidynamics and electrodynamics

Abstract

Lagrangian densities for spinor particles and photons in a gravitational field, including terms with C- and P-parity violations that remove degeneracy in spin states, are postulated. The modified Dirac and Maxwell equations are obtained. Hamiltonians for particles (bodies) possessing quantum (classical in the case of bodies) angular momentum are constructed in the semiclassical approximation. It is shown that the new interactions can produce the following effects: variation of body weight because of the partial spin ordering of electrons and nucleons, angular splitting and the relative retardation of left- and right-handed polarized waves passing near the Sun, modification of atomic spectra and of the atomic shell structure, and generation of high-power X-rays in the vicinity of neutron stars and of isotropically distributed high-energy cosmic rays in the early Universe.
